Laser-assisted doubly charged Higgs pair production in Higgs triplet model (HTM)

TL;DR

This paper investigates how a circularly polarized laser field influences the pair production of doubly charged Higgs bosons in the Higgs triplet model, revealing that laser parameters significantly affect production cross sections.

Contribution

It provides a detailed theoretical calculation of laser-assisted Higgs pair production cross sections, incorporating both Z and photon diagrams, and analyzes their dependence on laser parameters and Higgs mass.

Findings

Laser-assisted cross section decreases with increasing laser intensity.

Cross section diminishes as laser frequency decreases.

Higher Higgs mass leads to lower production cross section.

Abstract

In the framework of Higgs triplet model (HTM), we study the pair production process of doubly charged Higgs bosons via $e^{+}e^{-}$ annihilation in the presence of a laser field with circular polarization . We begin our work by presenting the theoretical calculation of the differential cross section in the centre of mass frame including both $Z$ and $\gamma$ diagrams. Then, from the numerical analysis of the production cross section's dependence on the laser field parameters, we have shown that the laser-assisted total cross section decreases as far as the electromagnetic field intensity enhances or by decreasing its frequency. Finally, we analyze the variation of the total cross section versus the mass of the doubly charged Higgs boson by fixing the laser field parameters and the centre of mass energy, and we have found that the order of magnitude of the cross section decreases as long as $M_{H^{\pm\pm}}$ increases.
